Homicide detectives appealing for information in their investigation of a retiree murder

Grandfather-of-seven Antonio "Tony" Salaris was looking forward to practicing his guitar shortly before he was stabbed to death near his Melbourne home in a killing that has baffled police.

The 73-year-old retiree was found lying on the ground by a neighbour after being fatally stabbed a number of times by an unknown man near his property on Browning Street in Kilsyth shortly before 9am yesterday.

Homicide detectives said today they were no closer to discovering the identity of the killer or his motive, and appealed for witnesses to come forward.
